Early changes in pulmonary function after stereotactic body radiotherapy for lung oligometastases

Key Points

• The study aims to assess early changes in pulmonary function following stereotactic body radiotherapy (SBRT) in patients with lung oligometastases.
• Evaluated pulmonary function parameters after SBRT
• Monitored airflow parameters, lung volumes, and gas exchange
• Considered factors like NSCLC histology, inflammation, and metastasis size
• Detected modest early declines in airflow parameters post-SBRT
• Lung volumes and gas exchange remained stable
• Identified age, systemic inflammation, and metastasis size as potential risk factors for declines
